Deskstar XP SCSI-2 Fast
Jumper settings
Model: DPES-30540, 30810 and 31080
Jumper position and function are as
shown below. Pin pitch is 2 mm. The jumpers control SCSI
Device ID, Auto Spin Up, Unit Attention, SCSI Terminator Connection,
and Target Initiated Synchronous Negotiation.
Notes:
- If JP4 is Off, the drive will spin up automatically after
power on reset. If JP4 is On, the drive will not spin up
unless the host system issues a start command to the drive
with the start bit set to one.
- If JP5 is On, Unit Attention after power on reset or SCSI
bus reset is disabled.
- If JP6 is On, the internal SCSI active terminator works.
- If JP7 is On, Target Initiated Synchronous Negotiation is
disabled, and then the Initiator is required to start a
negotiation handshake if Synchronous SCSI transfers are
desired. On drives manufactured after 3/95, JP7 will be
the LED drive lines.
